Reference to the above table will lead the following conclusions as 

 to Akamatsu and Kuromatsu: — 



(1) Growth of the Stem. 



Seedlings obtained from the seeds of colder localities are in their 

 early stages slower in growth ; later, however, such a similarity disappears 

 and seedlings from seeds of cold and warm sections become alike in 

 development. 



(2) Number of Trees bearing Flowers. 



There is no distinction with regard to number of flowers borne 

 according to localities from which seeds are obtained. Young mother 

 trees, however, give rise to more seedlings that bear flowers, and this is 

 especially remarkable in the case of Sugi. 



In general, the -result of the experiment on these species, Aka- 

 matsu and Kuromatsu, did not give such a marked distinction as was 

 expected, and this may be attributed to the fact that their growth was 

 not in normal state. 



Sugi, however, unlike the other two conifers, showed distinctions 

 which may be summed up as follows: — 



1. Relation Between Age of Mother Trees and 



Sugi Saplings obtained therefrom. 



In the case of seedlings that have been transplanted several years 

 in the forest, no such marked distinction is observable as existed in the 

 younger days between those from young and those from old mother 

 trees. In Tokyo, saplings originating in young trees showed a somewhat 

 better growth than those from old trees while in Owashi this superiority 

 was very clearly marked. 



2. Growth of Saplings from Seeds of different 



Localities compared. 



In proportion to the differences of the climates of the producing 

 districts saplings keep the distinctions shown in their seedling days and 

 these become still more striking with the advance of years so that no 

 uniformity is arrived at. Especially in colder districts such as Akita the 

 growth is every slow and it cannot be said how long such slowness in 

 growth will continue.
